NIIE rrns N. Y., ASSIGNOR TO MANNS BOUDOIR GAR COMPANY, OF SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 311,021, dated January 20, 1885.

Application filed May 14, 1884.

To all whom it may concern Be it known that I, WILLIAM DALToN MANN, of the city of New York, in the county and State of New York, have invented certain new and useful Improvements in Heating Apparatus for Railway-Oars; and I do hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to improvements in the apparatus used for heating railway-cars, and has for its object the provision of simple and'ready means for affording a supply of fresh hot water for lavatorial and buffet'purposes at all times when the ear is in service and when same may be desirable.

For a nore thorough comprehension of my invention reference must be had to the accompanying drawings, in which Figure I is a transverse section near one end of a car, which is broken and reduced in height, so as to show the corners, in one of which is located the heating apparatus, and in the other the wash-stand, past which the hot-water pipe is carried, being provided with a cock for drawing off the Water,wherever it may be desired. Fig. II is a similar view showing the employment of a coil for heating the water instead of a jacket, as represented in Fig. I.

A represents the base of the heater.

Bis the ash-pit, provided with a suitable door with dampers b.

O is the grate, of any suitable construction, and carrying the fire-pot C, in the interior of which is arranged the usual coil, D, through which the water used for heating the car is passed. This coil preferably extends for some distance above the fire-pot, and its ends are carried out through casing E of the furnace, so that the inlet D and outlet D will be ar ranged substantially as shown.

Frepresents the flue or smoke pipe,arranged preferably in a vertical line with the center of the grate 0.

D represents the tank containing the water for heating purposes, said tank being provided with a filling-funnel, d, and a safetyvalve, d, to permit the escape of any super fluous steam.

G is a tank containing water for lavatorial 5o purposes, which may be situated in any suit- (No model.)

able and convenient part of the car, and filled by any suitable means, but preferably through a pipe, G, passing through the roof of the ear and closed by a stopper.

H is a service-pipe, which is connected at its end H with the upper portion of the tank G, and at its end H with the lower part of said tank, said pipe being employed for conveying the water for lavatorial purposes to any desired part or parts of the car, said wa- 6o ter being heated by passing through a water jacket, tank, or coil, I, located on the outside of the stove or heater, as hereinafter described. WVhen a coil is employed, as represented in Fig. II, the end H is connected with the up- 6 5 per end of said coil, and the end H with the service-pipe H, which is carried completely around the car, returned to the heater, and connected with the lower end of the coil. It will thus be seen that by making a complete circuit around the car and through the heating coil and tank a constant circulation is maintained, thereby keeping all the lavatorial water at an elevated temperature. When a water jacket or tank is employed, as repre- 7 sented in Fig. I, the end H is connected with the upper and the end H wit-h lower portions thereof, respectively, the service-pipe H being itself connected at its respective ends to the upper and lower portions of said tank also. It will thus beseen that a constant circulation will be maintained through the jacket I, pipes H and H, and tank G, and also through the jacket I and service-pipe H, with the same effect as above described. (Jocks J may be 8 3 placed at any desired points throughout the pipe H, said cocks being tapped directly into said pipe H itself, or into a branch, h, thereof. Any surplus steam generated in the tank or reservoir G will be carried off by a suitable o overflow-pipe, K. I

This invention differs fron 'anything heretofore employed, inasmuch as it has for its object the provision of a tank containing water for lavatorial purposes, and suitable means 9 5 for heating and pipes for distributing said wa ter independent of the tank and pipes used for heating purposes. This is ,highly desirable, as it is found expedient to employ brine for the lat-ter purpose,whicl1, of course,[is not suitable IOO for washing. Suitable taps and valves will of course be provided throughout the system, by which the supplyand direction of the hot water will be regulated.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. In a railwaycar, the combination, with a stove or heater, a tank, and pipes for maintaining a circulation of hot water throughout the car for heating purposes, of a second tank containing water for 1avatoria1 purposes, and an independent system of pipes (conveying said water into contact with the heater) tapped for drawing'off said water for use, as described.

2. In a railway car, the combination, with a stove or heater, of two separate and inde pendent hot-water circuits, one consisting of a reservoir and suitable pipes conducting hot water therefrom throughout the car for heating purposes, returning it to said tank through the heater, whereby its temperature is again raised, and the other consisting of a reservoir and similar circulating-pipes, whichare tapped at desired parts of the car for drawing off water for use, as described.
